Replacement Power Supply for Colour Touch 5080-CTC1, CTC2 and CTC3

Hi All,
I would like to know if their is any interest in the availability of replacement power supply units for the colour touch screens.
If there is sufficient interest we will be in a position to provide these units for each of the 3 different unit types, fitted with the appropriate DC power connector.

We are already providing a repair service for these units and would like to also be in a position to provide the power supplies as well, but need to show our management that there is interest in them as we would need to purchase a minimum number due to the specific output requirements.

Best Regards and have a great day,
Trevor Callaghan

Used you recentlyTrevor to repair a Colour Touchscreen absolutely brilliant service couldn't recommend you higher
Thanks Martyn

 

Just a quick update, we are currently testing a replacement power supply, that will be suitable for both the CTC1 and CTC2 units. If all goes well, we should have this available from mid to late August for sale.
We are also looking at getting a replacement for the CTC3 version as well.

regards
Trevor

 

Due to certification requirements the current power supplies we were investigating turned out to not be suitable for the Australian market. I will endeavour to keep looking for a solution as I'm continuously made aware their is a requirement for replacement power supplies.

Hi Again,
just another update, I'm still looking for appropriate replacement power supplies for the touch screens.
In the mean time, until I do have a solution we can provide directly from us, here are some possible solutions...

CTC1 and CTC2 - Jaycar has a Mean Well 70W 5V 14A Power Supply (MP3289). It is an open frame type and for this reason I am unable to offer it directly. It can be adjusted to provide the required output to drive the units, you will need to splice the DC cable from the AC/DC power pack or the DC/DC (small box)

CTC3 - a generic 24 Volt 10 Amp power supply (off the shelf) will work with these units

I'll keep looking for a better solution in the mean time.

 

Hi Ashleigh,
Arbor Australia originally designed and built these units for Clipsal. The internal power regulation on all 3 types is based on a buck boost power supply arrangement, this in turn provides the power to drive the internal regulators throughout the unit, and there is a lot of them. The CTC1 power supply is only an output power device it has no feedback regulation, the 4 pins are a double up of positive and negative conductors. The CTC2 uses the small DC-DC regulator box between the AC-DC power pack and the unit, it gets feedback from the CTC2 and keeps the input voltage stable to the unit. It has a 7 pin connector going to the CTC2, 3 pins each for plus and minus and one for the feedback.

The CTC1 does use a reverse voltage protection diode and drops 0.7v across it when powered up.
The CTC2 uses the DC-DC converter to do this and is more stable as it provides an output to the unit after the protection CCT.

You are also correct about the output voltage needing to be correct at the input to the CTC1 and CTC2, this is why Clipsal had the original power packs made to output 5.3 Volts for the CTC1 and 5.6 Volts for the CTC2.
The CTC3 power supply is a standard 24 Volt DC output with no feedback, it only uses 2 pins.

The Mean Well power supply will drive these units as I have had several customers bring in their units and get me to adjust them here so they do work correctly. I have also done this over the phone for some end users to set theirs correctly as well.

I am only a technician, so am limited in knowledge of the reasons behind the design , but the original engineer who did do the design still works for Arbor, if anybody has any questions I can relay them to him and reply here.

 

Hey @Trevor (and all) . I have a new never used CTC2 touch screen with no power supply. have bought a Mean Well MDR-40-5 (40watt 5v) and connected it up via a 7pin Din plug. I used the pinout from here https://www.cbusforums.com/attachments/5080ct02-supply-small-jpg.2005/

When I connect the CTC2, all I get is a relay clicking sound around 2 times per second. I measure the voltage which is sitting steady at 5.6v. If I adjust this up or down a little it makes no difference to how the CTC2 responds. Any thoughts on what could be wrong? I notice you recommended the 70W Mean Well supply. Is mine under-powered?

I have quite a long cable also so not sure if this is a factor.

 

The ticking is indicating there is not quite enough power getting in
try tweaking it up to max, but don't go over 6v. let me know if it works,
regards Trevor

 

Hey @Trevor . Did that. Cranked it up to 6v but it made no difference. Relay still clicking.

 

Hi,
I'm surprised to here that, how are you connecting the power supply, is it direct into the unit?
Were are you measuring the voltage? it needs to be 5.6v at the input of the unit. The cable could be dropping a lot over it. Can you shorten it? I have some spare dc-dc converters that plug into the unit, your ac/dc psu could drive that first, it will keep the voltage at 5.6 they are on sale for $150 Ex GST
Give me a call if you like.

Hi @Trevor you were on the money there, thanks. I shortened the cable by a lot and now the unit powers up fine. I have noticed however that the welcome screen only stays on for 2-3 seconds before it goes blank. Should I assume this is normal as I haven't configured the unit yet or connected to c-bus?

 

Hi Will,
Glad to here it, as i said on the phone, the welcome screen is like a bios slash screen and only shows for the amount of time then the system continues to reboot.

regards
Trevor

 

Hi All,
I've just had Trevor's email addres bounce on me, so hoping that this is just a temporary technical issue. But if not, can anyone point me in the direction of a replacement power supply for a C-Touch CTC1? It's the four pin type.
Thanks,
Glenn.

Hi Glen,
That email should work...its current
But you can get the psu from jaycar, its a 5v 14a adjustable meanwell about 50 bucks
Make sure you tweek it up to 5.6v or it wont work
